Abstract (en)

[origin: EP0790721A2] In a network system for effecting signal transmission by plural channels, there are provided plural channel alteration units each of which is adapted to receive signals through plural channels and to output each of the signals entered by said plural channels in any of plural channels. Transmission control is executed in such a manner that mutually proximate plural signals, which have to be outputted by a designated same channel among the plural channels from a first one of the plural channel alteration units, are entered through respectively different channels into the first channel alteration unit. As the first channel alteration unit receives the plural signals by different channels, there can be resolved the drawback of a long waiting time for the output of the signals by a desired channel, encountered in case the signals are entered by a signal channel. <IMAGE> <IMAGE>
